ISS Science for Everyone

Science Objectives for Everyone
The Onboard Diagnostic Kit (Onboard Diagnostic Kit) is a noninvasive, health-monitoring system capable of measuring, storing, and analyzing crewmember medical data while onboard the International Space Station (ISS). The medical data collected onboard are sent to the ground immediately, whereby doctors can quickly diagnose crewmember health.

Science Results for Everyone

That device Dr. McCoy, "Bones," used to diagnose illnesses on the Starship Enterprise may one day be real. The Onboard Diagnostic Kit, a noninvasive system that measures, stores, and analyze medical data from crew aboard the station using a digital Holter, pulse oximeter, USB camera, stethoscope, and electroencephalograph. Data are immediately sent to physicians on the ground and with this system, the sound of an astronaut’s heartbeat is heard simultaneously on the station and on the ground for the first time. Monitoring heart functions is critical to crew health during long-duration space flights.

    Results/More Information

    Various medical data were collected and downlinked to investigate the performance of the system. After the measurement of each data, the crew recorded their feedback and suggestions to assist in the evaluation and upgrade of the system.  JAXA Astronaut Satoshi Furukawa's 5 and a half-month mission allowed for the execution of an initial checkout of equipment and 3 sessions of data acquisition. A digital Holter, a pulse oximeter, a USB camera, a stethoscope, and an electroencephalograph were used to measure each healthcare data.  The collection of medical data was loaded into the ODK software on the laptop and several graphs were generated. From the view point as a medical doctor, Astronaut Furukawa evaluated the operability, visibility, and data interfaces of the ODK system and had discussions with ground support medical doctors while reviewing the electronic medical recoding system (electronic chart) simultaneously through the real-time health consultation between ISS and Tsukuba Space center.

    Astronaut Akihiko Hoshide who is not a medical doctor has performed 3 to 5 sessions of data acquisition. He has also evaluated the operability, visibility, and data interfaces.  Real-time downlink from the Electric Stethoscope was performed using the wireless communication technology that allowed ground support doctors to clearly hear the sound of the Astronaut Akihiko Hoshide’s heartbeat. So this is the very first time that the clear sound of a heart’s beat was simultaneously shared between ISS and the ground. In this session, we used S-band for the voice communication and K-band for data downlink of USB camera image and auscultated heart sound.
